Took a trip to Calgary to visit a few friends, they insisted we go to Peter's. Being from the US, I'd never heard of this place, but I love milkshakes so I put up no resistance. I ordered a plain cheeseburger and a shake. The food was good, nothing to write home about, but good! The reason for the low rating is their severe lack of customer service. I paid with USD, which they accepted after a moment's hesitation, but refused to compensate for the different values between USD and CAD. I asked if I could get my money back and pay with my debit card instead, but I was refused and told I was holding up the line.
